ii. ACV, DCV, Hz, ACA and DCA range
Turn the rotary switch to ACV, DCV, Hz, ACA or DCA range, the Meter displays digital reading
(Multimeter mode). Press Mode to switch to waveform display (scope mode) as below Figure 4. When
entering scope mode, time base is auto trace, the amplitude is manual set, you may need to re-set them.
You could set the trigger level as well if it is needed. Details of measurement operation of ACV, DC, Hz,
ACA or DCA can be seen from B. Digital Multimeter Mode:

z Press Range to switch between DC and AC measurement.
z When the frequency and amplitude of a waveform is unknown, press Auto:
¾ When the amplitude is set to auto, the amplitude indicator will be shown white text in black
background. When the amplitude is set to manual, the amplitude indicator will be shown black text in
white background.
¾ When the time base is set to auto, the time base indicator will be shown white text in black
background. When the time base is set to manual trace, the time base indicator will be shown black
text in white background.
¾ When the time base is between 20ms – 100ns, it is possible to set the auto. When the time base is
between 50ms – 5s, the auto feature will be in valid.
z Y-axis adjustment: Press Range button under scope mode, the corresponding functional button:
Move ▲ Move ▼ Rang ▲ Rang ▼
